Extremely quiet weather-wise, but hot. Summer-like temperatures with highs in the 90s expected.

Overall pattern at 500 mb has a rather large ridge over the southern rockies with weak troughs off the West Coast and over the Great Lakes. Warm air advection along an 850 mb jet is keeping thunderstorms going over Iowa and northern Illinois along with the weak upper disturbance. Humberto is off the East Coast of Florida.

Ridging over the Ohio Valley becomes more amplified by Tuesday at 500 mb with 850 temperatures remaining about the same around 18 degrees c. The atmosphere is generally dry, so not much in the way of precipitation during this period.

Dew points rise slightly Monday which will allow for a few locations (mainly over semo, extreme southern Illinois and far west kentucky) to go just above 100 on the heat index.

The long term period begins with the mean ridge still holding firm over the Mississippi River valley, and Humberto drifting out to sea. Surface high pressure extends across the entirety of the Ohio and Mississippi River valleys. So a hot/dry forecast continues.

There is a low pressure storm system moving across the central Canadian interior, and dragging a cold front across the Great Lakes. However, the models keep the ridge strong, effectively shearing off any southern portions of this boundary, and we stay high/dry into Friday.

By Friday, the surface high pressure system has centered over southern Appalachia, and return flow southerlies inject a higher fetch of dew points. We accept the blend's push of 70f into the Ozarks/semo, and with another day of temps near/in the 90s, this may be just enough to touch off an isolated shower or storm out there. Otherwise, there's just no forcing in the atmosphere to get anything going, beyond the isolated heat of day possibility.

Another front looks to approach from the northwest next weekend. The ridge is holding strong over the eastern U.S., But this front may end up sneaking in enough to give our next best chance of rain...just beyond the scope of this package.

Summer temps continue, with lower 90s and upper 60s/near 70 daily. Dew points mostly in the 60s means heat indices for the most part stay out of the triple digits. An exception might be the Ozarks Friday afternoon, when the dew points near 70. Isolated shower/storm chances then may mitigate that impact, however.
